What is the antonym (opposite) of the word ‘Benign’?

Explanation

‘Benign’ describes something gentle or harmless, especially used in medicine to describe a non-cancerous growth, so its opposite is ‘malignant,’ meaning harmful or, in medical terms, cancerous, as in ‘The biopsy confirmed the tumor was benign rather than malignant.’ The other three options are all synonyms of ‘benign,’ making ‘malignant’ the correct antonym.
